Given:
Ellen flipped a coin 80 times. The coin landed heads up 44 times and tails up 36 times.
To find:
The theoretical and experimental probabilities of the coin landing tails up and compare them.
Solution:
We know that, the coin landed either heads up or tails up. So, the theoretical probabilities of the coin landing tails up is



Ellen flipped a coin 80 times. The coin landed heads up 44 times and tails up 36 times.
Total = 80
Tails =36
The experimental probabilities of the coin landing tails up is



Therefore, the theoretical and experimental probabilities of the coin landing tails up are 0.5 and 0.45 respectively. The theoretical probability is greater than the experimental probability.
Answer:
x=1
Step-by-step explanation:
3x+2y=7
x-y+1=0
3x+2y=7
x-y=-1 /*2
3x+2y=7.... (1)
2x-2y=-2.... (2)
(1)+(2) 5x=5, x=5/5, x=1
